GitHub Username Takeover in conda-smithy Feedstock Repositories

Executive Summary

This vulnerability exists in conda-smithy versions prior to 3.61.0. Conda-smithy is a tool used to combine a conda recipe with configurations to build using freely hosted CI services into a single repository. The vulnerability allowed unintended write access to feedstock repositories through GitHub username takeover. The root cause was the use of mutable GitHub usernames as identifiers for routing repository invitations instead of stable, immutable GitHub user IDs.
